can any one help me out with this one?

headers are out
messing with the intake is out as this car is drive by wire and you fux that up............lol

??? How? Drive by wire only changes what opens the throttle. Either a motor, or a cable if it isn't drive-by-wire.

You could still change the intake manifold, or even get the throttlebody bored out if you wanted to. (I don't think there is an aftermarket intake manifold available for your car, but I'm just making a point)

you might want to check out some other sites becuase people have reported problems when messing with the intake.......and the DBW
